It is well known that an IC engine has an efficiency of about 35-40%‚ which means that only one-third of the energy in the fuel is converted into useful work and about 60-65% is wasted to environment. In which about 28-30% is lost by cooling water and lubrication losses‚ around 30-32% is lost in the form of exhaust gases and remainder by radiation‚ etc. In a Vapour Absorption Refrigeration System‚ a physicochemical process replaces the mechanical process of the Vapour Compression Refrigeration

Sufficient Homemade Air Conditioner Introduction and Background of the Study As day time is starting to become more and more unbearable‚ as fans would only constantly stir the hot sticky air S around‚ so the researchers ended up in choosing this topic. The researchers chose this topic mainly because of the hot weather here in the Philippines. The constant high temperature was the reason this came up to the researchers’ minds. This

Operation ENERGY BALANCES ACROSS THE FEED PREHEATING EQUIPMENT:The heating of cold 2-butanol feed is to be completed in three stages in order to avoid large heat losses. The cold feed is first preheated to its boiling point using steam as heating medium and then vaporized in a thermosyphon reboiler utilizing the heat contained in the reaction products. The vapor‚ which has entrained liquid is removed from the knock out drum‚ and then heated to reaction temperature

CHG 3111 Unit Operation Gas-Liquid Separation Text Book: Chapter 10 Separation Processes Introduction: Many chemical and biological processes occur as a mixtures of different phases‚ gas‚ liquid and solid. To separate or remove one or more of the components from its original mixture‚ it must be contacted with another phase. The two phase pair can be gas-liquid‚ liquid-liquid or liquid-solid. When different phases are brought into contact‚ a solute or solutes can diffuse from on phase to the
